1821490 - New tab page updates should pause when the user is away and resume immediately when the user is back

Status: RESOLVED FIXED

(Firefox :: New Tab Page, enhancement)

Description

[Florian Quèze [:florian]]

browser/components/newtab/lib/SystemTickFeed.jsm uses a repeating 5 minutes timer to update the new tab page. I think the intent is to ensure the data is always fresh, but this is wasteful when the user is away from the computer for an extended duration.

I think we could instead implement the following behavior:

• when the 5 minutes timer fires, if the user has been inactive from more than 5 minutes, remove the timer and instead add an observer to be notified the next time there is user activity.
• when there is user activity again, trigger an update immediately and restart the timer.
• to minimize the risk of the update getting in the way of processing user events, trigger updates using ChromeUtils.idleDispatch.
